The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test. Nuclear weapons design are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate. There are three existing basic design ...
Weapons-grade nuclear material is any fissionable nuclear material that is pure enough to make a nuclear weapon and has properties that make it particularly suitable for nuclear weapons use. Plutonium and uranium in grades normally used in nuclear weapons are the most common examples.
The S-50 plant is the dark building to the upper left behind the Oak Ridge powerhouse (with smokestacks). Groves contracted with the H. K. Ferguson Company of Cleveland, Ohio, to build the thermal diffusion plant, which was designated S-50. [170] Plans called for the installation of 2,142 48-foot-tall (15 m) diffusion columns arranged in 21 racks.
Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs (abbreviated as A-bombs). This has long been noted as something of a misnomer , as their energy comes from the nucleus of the atom, just as it does with fusion weapons.
In atomic physics and quantum chemistry, the Aufbau principle (/ ˈ aʊ f b aʊ /, from German: Aufbauprinzip, lit. 'building-up principle'), also called the Aufbau rule, states that in the ground state of an atom or ion, electrons first fill subshells of the lowest available energy, then fill subshells of higher energy.
If an atom has more electrons than protons, then it has an overall negative charge and is called a negative ion (or anion). Conversely, if it has more protons than electrons, it has a positive charge and is called a positive ion (or cation). The electrons of an atom are attracted to the protons in an atomic nucleus by the electromagnetic force.
What is an atom? Atoms are the building blocks of all matter and are made up of a nucleus and a number of orbiting electrons. Originally proposed in Ancient Greek philosophy, they were originally ...
Building a neutron source in his mother's backyard David Charles Hahn (October 30, 1976 – September 27, 2016), sometimes called the "Radioactive Boy Scout" and the "Nuclear Boy Scout" was an American nuclear radiation enthusiast who built a homemade neutron source at the age of seventeen.
